Tobacco use is an important risk factor for advanced periodontitis, poor response to periodontal therapy, oral neoplasms, and dental implant failure. Given the effect of tobacco use on oral health, the dental office may be an ideal place for tobacco cessation intervention, especially since a large proportion of smokers visit their dentist on a regular basis. This paper reviews various tobacco cessation strategies for the dental office and provides practical information on assessing patients' readiness to quit and choosing appropriate tobacco cessation interventions.

Use of bupropion SR in a pharmacist-managed outpatient smoking-cessation program.

Roth MT, Westman EC.

Ambulatory Care Clinics, Durham Veterans Affairs Medical Center, North Carolina, USA.

We administered bupropion sustained-release (SR) in a pharmacist-managed outpatient smoking-cessation program. Patients were referred to the program by their primary care physician. All patients completed initial visit questionnaires, received behavioral counseling by a clinical pharmacist, and were provided educational materials on smoking cessation. Seventy-one patients received bupropion SR for treatment of nicotine dependence and were followed for 6 months. Point prevalence abstinence rates were 28.2% and 25.4% at 8 weeks and 6 months, respectively. The trend was toward lower cessation rates in patients with a documented psychiatric diagnosis at 6 months (p=0.064). Bupropion SR was fairly well tolerated, with the most common adverse effects being dry mouth and bad taste. The agent appears to have better success for smoking cessation in patients free of psychiatric comorbidities, but further research is required to support this finding.

Bupropion hydrochloride: the development of a chiral separation using an ovomucoid column.

Munro JS, Walker TA.

Atrix Laboratories, Fort Collins, CO 80525-4417, USA.

The separation of bupropion enantiomers on an ovomucoid stationary phase was investigated. The mobile- and stationary-phase parameters that may influence the separation were identified. The parameters that were studied include: type and concentration of organic modifier, mobile phase pH, ionic strength, type of buffer, and column temperature, as well as the effect that the amount of sample injected had on the separation. The optimized chiral separation baseline-resolved the enantiomers in less than 10 min. Calibration curves for a standard were linear over a range of 0.27-53.0 microg/g (ppm) with a correlation coefficient of 0.999 for both enantiomers. A detection limit of 0.13 microg/g and a quantitation limit of 0.27 microg/g were also found. The system precision of the method was 0.2%.
